Texas Property Tax Protest Evidence: What Works and What Doesn't

Texas gives homeowners a second, distinct ground to win a protest: unequal appraisal, often called "equal and uniform." It can succeed even in a hot market where a pure market-value argument fails.

The legal standard. Under Tex. Tax Code §41.43(b)(3), a protest on the ground of unequal appraisal shall be determined in favor of the property owner unless the appraisal district establishes that your appraised value is equal to or less than the median appraised value of a reasonable number of comparable properties, appropriately adjusted. In other words, you are entitled to be taxed no higher than the median of comparable homes — regardless of what your house would actually sell for.

Why it is powerful. A market-value protest asks whether your value is too high relative to sales. An equal-and-uniform protest asks whether you are being treated fairly relative to your neighbors. In appreciating markets, sales may support a high value, but if near-identical homes are appraised lower, you can still win a reduction to the adjusted median.

Building the case:

• Pick comparable accounts — similar homes in your area by size, age, quality, and condition. You can pull these from your appraisal district's public records.
• Adjust appraised values, not sale prices, for differences (square footage, lot size, condition, extras).
• Compute the median of the adjusted appraised values. If your appraised value exceeds that median, request a reduction to it.
• Request the district's evidence by checking the box on Form 50-132 so you can rebut their comparables under Tex. Tax Code §41.461.

Burden of proof. As the Texas Comptroller notes, you must come prepared with evidence — but on the unequal-appraisal ground, the statute places the burden on the appraisal district to prove your value is not above the adjusted median. Mark both "over market value" and "unequal appraisal" on your protest to preserve both arguments.

One of the most undervalued tools in a Texas protest is your right to demand the appraisal district's evidence in advance.

The right. Under Tex. Tax Code §41.461, at least 14 days before your hearing the chief appraiser must inform you that, on request, you are entitled to a copy of the data, schedules, formulas, and all other information the chief appraiser will introduce at the hearing to support the value. You trigger this by checking the evidence-request box on Form 50-132 or by sending a written request.

It is free. The statute bars the chief appraiser from charging you for these copies, regardless of how they are prepared or delivered. On request, the district must provide them by first-class mail or in person at the appraisal office.

The teeth. This is the part most homeowners miss: information that you requested but the district did not deliver to you at least 14 days before the hearing may not be used or offered in any form as evidence at the hearing — not as a document, and not through argument or testimony. If the district shows up with comps or a valuation model it never sent you, you can object and ask the ARB to exclude it.

How to use it strategically: 1. Always check the box when you file. There is no downside. 2. Request the district's evidence early so you have time to study it. 3. Study their comparables — they reveal exactly how the district justified your value, and often expose comps that are larger, newer, or in better condition than yours. 4. Build your rebuttal around the weaknesses you find, and prepare your own comparable-sales or equal-and-uniform evidence under Tex. Tax Code §41.43.

The Texas Comptroller reminds owners the burden is on them to prove their case — seeing the district's hand 14 days early is the single biggest advantage you can claim.

If you missed the protest deadline or discover a factual error in a past year, Texas has a back door: the 25.25(c) correction motion.

What it covers. Under Tex. Tax Code §25.25(c), the Appraisal Review Board, on a motion by the chief appraiser or by a property owner, may order changes to the appraisal roll for any of the five preceding years to correct:

• a clerical error;
• multiple appraisals of the same property (taxed twice);
• the inclusion of property that does not exist in the location or form described; or
• an ownership error showing the property in the wrong name.

Why it's valuable. Unlike a regular protest, a 25.25(c) motion is not bound by the May 15 deadline and reaches back up to five years. It is ideal for objective record problems — your property record card lists 2,500 square feet when the home is 2,000, shows a bathroom or outbuilding you don't have, or describes land you don't own. These are factual, high-success corrections.

What it does NOT cover. Section 25.25(c) is for the specific errors listed above — it is not a way to re-argue market value or unequal appraisal after the fact. A simple disagreement about value belongs in a timely protest under Tex. Tax Code §41.41, or, for a very large overvaluation, in a 25.25(d) substantial-error motion.

How to file: 1. Get your property record from your appraisal district and identify the specific factual error. 2. File a written motion with the ARB (many districts provide a correction-motion form) describing the error and the years affected. 3. Attach proof — a survey, builder plans, an appraisal, or photos establishing the correct facts. 4. Attend the hearing the ARB sets on your motion and present your evidence.

The Texas Comptroller describes these correction remedies as available in addition to the ordinary protest. If the error inflated your value, a correction can also produce a refund of overpaid taxes for the corrected years.

When your value is dramatically too high and the protest window has closed, Texas offers a substantial-error remedy under 25.25(d).

The threshold. Under Tex. Tax Code §25.25(d), a property owner (or the chief appraiser) may file a motion with the Appraisal Review Board to correct an error that resulted in an appraised value that exceeds by more than one-third the correct appraised value. The popular nickname "one-fourth rule" is imprecise — the statutory test is a value overstated by more than one-third (i.e., the assessed value is more than 1.333× the correct value).

The timing. The motion may be filed at any time before the date the taxes on the property become delinquent — which gives you a window well past the May 15 protest deadline. This makes it a genuine safety valve for a homeowner who missed the protest or whose value is wildly off.

The catch — a penalty. A correction under §25.25(d) is not free of consequence. If the ARB grants the motion, the property is subject to a late-correction penalty equal to 10% of the amount of taxes calculated on the basis of the corrected appraised value. So the remedy reduces your value substantially but adds a penalty on the corrected tax — weigh that before relying on it instead of a timely protest.

When to use which remedy:

• Timely protest (by May 15) under §41.41 — always the first choice; no penalty, any grounds.
• §25.25(c) correction — for clerical errors, double appraisals, or non-existent property, up to five years back, no one-third threshold.
• §25.25(d) substantial-error motion — when the only path left is a current-year value overstated by more than one-third and you accept the 10% penalty.

How to file: submit a written motion to the ARB identifying the property, the current appraised value, the value you contend is correct, and evidence (appraisal, comparable sales) showing the overstatement exceeds one-third. The Texas Comptroller lists the §25.25 motions among the remedies available outside the ordinary protest. Do the math first: confirm the overstatement clears the one-third bar, since a smaller error won't qualify.
